TO ALL WHOM IT MAY CONCERN:

Be it 'lrnownthat I, ADRE FOUBERT, ofthe city and State of New York, have invented and made a certain new and useful Improvement in the Manufacture of Vinegar; and I do hereby'declare the following to be a full,

clear, and exact description oi the said invention, reference being had to the annexed drawings, making part of this specification, w'hereini Figure 1 is a vertical section of the apparatus employed by me, and

Figure 2 is a sectional plan at the line y y.'

The same parts are marked with corresponding letters.

In Letters Patent granted to me, March I9, 1867, an apparatus for manufacturing vinegar is shown, in which the vapors from the mash or light-wines are condensed'by water and a small proportion o'- vinegar or acetic acid, and trickle over shavings for exposing the liquid to the atmosphere and forming vinegar.

My present invention is an improvement upon the said` invention, and consists in a tub in which are evaporated the light-winesfrom mash or shavings, or other fermented material, said tub containing concentrating platforms and a screen that admits a shower of acidulatedwater to condense the vapors. The liquid runs out bv a pipe, and flows over the shavings in a vat, so that the liquid is turned into strong vinegar.

The operation of this apparatus corresponds generally with'that in said patent, but the construction is different; n I i In the drawing, a is a tub, in which are the platforms b,'c,ancl el, havingvapor-tubes e and caps z', andf and g are return-tribes to the tub; his a coil, supplied with water to cool the liquid on the platform e. 7c is a vessel containing vinegar, and l is the vessel for water, and m is a perforated plate or sprinkler.` n is the pipe i to the shavings-tub o.

The mash, wine, or wasn is introduced into the tub a to the desired height, indicated by the glass gauge 2J. Steam is admitted to the coil q, and the evaporation passes through the vapor-tubes c, and the liquid upon the platforms b and c, which condenscs the essential oilsand more lwatery portions, which are returned to the tub.

The uncondensed vapors passing into the liquid on the platform i warm the same, and are iinally condensed by the shower from theperforated plate m; the liquid then passes in a warm condition into the shavings-tub o.

v The proportion of vinegar from the vessel 7c, and water from the vessel Z, is to be regulated by the cocks, and I nd practically that the production of a superior quality of vinegar with a small supply of vinegar from the vessell lc is insured, and that the use of any other acid than acetic is unnecessary. l Y

The tub o, containing the shavings, may be of any desired size, and the liquidretained therein by the cock o1, a glass tube, o2, indicating the quantity, and allowing an escape of air from the tub.

'From the tub o the vvinegar is allowed to flow over shavings in any desired number of tubs, according to the strength required. I have shown the tubs a: :o a: x, each provided with a perforated plate at v, to cause the liquidto be evenly distributed over the shavings.

What I claim, and desire to secure by Letters Patent, is-

An evaporating-tub containing` platforms and vapor-tubes, in combination with the apparatus for supplying water and vinegar, and with the vat containingshavings, substantially as and for the purposes set forth.

In witness whereof, I have hereunto set my signature, this iii-st day of February, 1868.
